Fatty acid concentrations in preterm infants fed the exclusive human milk diet: a prospective cohort study.

Objective: Quantify blood fatty acids and growth outcomes in preterm infants fed the exclusive human milk diet.

Methods: A prospective cohort study of 30 infants 24-34 weeks gestation and ≤1250 g fed the exclusive human milk diet. Blood fatty acids were quantified at two time points.

Nursing blood specimen collection techniques and hemolysis rates in an emergency department: analysis of venipuncture versus intravenous catheter collection techniques.

Introduction: Re-collection of hemolyzed blood specimens delays patient care in overcrowded emergency departments. Our emergency department was unable to meet a benchmark of a 2% hemolysis rate for the collection of blood samples. Our hypothesis was that hemolysis rates of blood specimens differ dependent on the blood collection technique by venipuncture or intravenous catheter draw.

Arabidopsis SGT1b is required for defense signaling conferred by several downy mildew resistance genes.

We describe the identification of a mutant in the Arabidopsis accession Columbia (Col-0) that exhibits enhanced downy mildew (edm1) susceptibility to several Peronospora parasitica isolates, including the RPP7-diagnostic isolate Hiks1. The mutation was mapped to chromosome IV and characterized physically as a 35-kb deletion spanning seven genes. One of these genes complemented the mutant to full wild-type resistance against all of the Peronospora isolates tested.
